SIPEOIFIOATION forming part of Letters Patent No. 617,225, dated January 3, 1899.

Application filed April 14,1898. Serial No. 677,583. (NomodeL) To all whom it ntcty concern:

' Be it known that LOYRU's COOPER, of Tiverton, in the county of Ooshocton and State of Ohio, have invented a new and Improved Neck-Yoke, of which the-following is a full, clear, and exact description.

This invention is a neck-yoke designed to be attached to the poles of two-horse vehicles, and the neck-yoke is so constructed that it may be readily connected with and disconnected from the pole and also have that freedom of movement necessary to its effective operation, the construction also operating to prevent the accidental displacement of the neck-yoke.

This specification is the disclosure of one form of myinvention, while the claims define the actual scope of the invention.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both figures.

Figure 1 is a perspective view of the inven tion applied, and Fig. 2 is a side elevation of the headed arm whereon is carried the neckyoke.

The'pole or tongue 3 of the vehicle is provided at its forward end with an upper metallic plate 4 and a lower metallic plate 5, fastoned securely to the tongue and projecting forwardly beyond the same. Passing through the front extremities of the plates 4: and 5 is a pin 6, which holds, to turn on a vertical axis, a block 7. The block 7 is fixed rigidly to or formed integrally with the arm 8,and the front end of the arm 8 has a fiat head 9, disposed vertically. The neck-yoke 10 may be of any desired construction and is provided centrally with a slot 11, elongated longitudinally with the neck-yoke. This slot receives the arm 8, as indicated in Fig. 1. By these means the neck-yoke is connected with the tongue.

In applying the neck-yoke it is moved to a vertical position, as indicated by the dotted lines in Fig. 1, whereupon the fiat head 9 may pass through the slot 11 of the neck-yoke,and then by turning the neck-yoke a quarter-way around the head 9 engages with the neck-yoke crosswise the slot, so that the displacement of the yoke cannot be effected unless the yoke be moved back to a vertical position. This mounts the yoke so as to swing freely with the arm 8 and block 7 on the vertical axis of the block, such axis being formed by the pin 6.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination with the pole of a vehicle, of two plates secured thereto and projecting forwardly beyond the pole, a pin passed vertically through the front extremities of the plates, an arm having one end provided with a block fitting between said front extremities of the plates and mounted to swing on a vertical axis formed by said pin, the arm also having a fiat head disposed vertically, and a neck-yoke having an intermediately-located slot disposed longitudinally with the neck-yoke, the slot being capable of permitting the passage of the said head when the neck-yoke is in vertical position, and the head serving to prevent the displacement of the neck-yoke when the same is in horizontal position.

2. The combination of an arm, having at one end a vertically-disposed head, and having at the other end a block adapted to be mounted on the pole of a vehicle so that the block may swing on a vertical axis, and a neckyoke having an intermediately-located slot elongated longitudinally with the neck-yoke, the slot permitting the passage of the head when the neck-yoke is in vertical position, and the head preventing the displacement of the yoke when the same is in horizontal posi tion.

3. The combination of an arm adapted to be mounted to swing on a vehicle-pole, the

axis of the armbeing vertical and the arm having at its free end a Hat head disposed vertically, and a neck-yoke having an intermediately-located slot disposed longitudinally with the neck-yoke, the slot permitting the passage of the head therefrom when the neck-yoke is in vertical position and the head 9 5 preventing the displacement of the yoke when the same is in horizontal position.

- CYRUS COOPER.
